Abstract

Aim. To analyze prevalence and variability of Legionella strains isolated in town Verkhnaya Pyshma located in Sverdlovsk region during prophylactic surveillance of potentially dangerous water objects in 2007 — 2008. Materials and methods. Sequencing of mip gene was conducted for identification of species of Legionella . Multi-locus sequence typing was used for describing of allelic profiles of Legionella pneumophila strains. Results. Five firstly identified on Russian territory strains of Legionella species were deposited in institute’s collection. Sixty-three strains of L.pneumophila belonging to 28 sequence types were characterized. Relation between strains isolated in industrial building and from water supply system was demonstrated. Conclusion. Observations made on the basis of study of L.pneumophila strains isolated from cooling stacks of industrial plants confirmed potential danger of these objects as a source of dissemination of Legionella infection.
